I bet you the AAV for Bourn + Prado < AAV for the Uptons over the next 3 years.
Basically, Bourn isn't getting more than Upton (Heyman, who is Boras' mouthpiece, basically admitted that Boras was only looking to replicate Upton's contract for Bourn at this point). That means Prado, who's going to get about $7 million this year, would need to get $32 million over the next two years to equal what the Braves are going to pay Justin Upton (3/$39 left).
Prado's not getting that.
